The former congresswoman and her husband tapped Wayne LaPierre, executive vice president and CEO of the National Rifle Association, to be next up in this summer’s viral cause.

“We hope one day we can agree upon more than just supporting ALS and Lou Gehrig’s disease research,” says Kelly, before getting a bucket of freezing water dumped on his head.

Giffords, who was shot in the head in 2011, and Kelly are now leading advocates against gun violence through their Americans for Responsible Solutions organization. The NRA, the nation’s largest gun rights group, has opposed legislation sought by Giffords and Kelly to expand background checks for gun buyers.

The Ice Bucket Challenge has raised $41.8 million through Thursday to help strike out Atromyotrophic lateral sclerosis, a disease that affects nerve cells in the brain and spinal cord. This year is the 75th anniversary of baseball icon’s Lou Gehrig “luckiest man” speech. He died of ALS in in 1941.

Giffords has made tremendous strides since 2011 but has trouble communicating because of aphasia.

In their video to show they accepted the challenge of Democratic National Chairwoman Debbie Wasserman Schultz, Giffords stands next to her husband. Kelly explains the Ice Bucket Challenge and why they are nominating LaPierre — as well as his twin brother, astronaut Scott Kelly, and Jimmy Hatch, a former Navy Seal who accompanied Giffords on her first skydive to mark the third anniversary in January of the assassination attempt on her life.

“Good job,” Giffords said through her laughter after Kelly got doused.
